👉 A contradiction is a situation in which there are two contradictory statements or propositions that cannot both be true at the same time. In other words, it is a statement that has a "no" answer to it and does not have any truth values. For example, if you say "I am an adult," then you must also say "I am a human being." If one of these statements is true, then so must the other, but they cannot both be true at the same time.
